Be it known-that I, WILLIAM A. BERNARD,

a citizen of theUnited States, residing in;

for applying or-settingstaples and like fasn teners, and it hasparticular reference to hand tools designed to apply buckles-and bows toshoes by means of: thesmall staples which aregenerally used for thispurpose. The invention other uses. a v r The primary object which I haveinview is the provision of an efficient, reliable device for driving orpushing a staple through a plurality of superposed layers of material,andthen' clenching the ends of'the, staple in thematerial so as to'forma strong, tight connection between the, layers; 5

Anothenobject is to provide a device which, can be very convenientlyoperated, inasmuch as-means are provided for receiving and retaining thestaplein the proper positionpreparatoryto and durin the piercing, andclenching operation, without the'necessity of exercisingvspecial .carein positioning the staple oroperating the 'tool ordevice. r

I also aim to providera staple applying device in which the staplecanbeset-indifferent positions relative tothetool, without adjustingthelatter. Moreparticularly, it is aimedtfo provide a] tool in, which thestaple when in position for application to, theshoe or other article,can be directed eitherlongitudinallyortransversely of the toolso that itcan be placed in'the mostadvantageous position-on the article applied.

to which it is to be To these and other ends,- the invention consists inthe novelfeaturesfand combinations of parts to be hereinafter 1described and claimed. v i

of other types. In the form shown,:the tool comprises crossed levermembers lO, 11 piv-.

oted together at-12, and parallel jaws-'13, 14 movable toward and awayfrom each other. The aw,14 is equipped-with a member 15 for driving thestaple through the material, and associated with saidmember is a stapleopeningin the j aw:14. "It serves as a guide for the holder 16, which-isin the form of a sleeve embracing the driver and vertically movable withrespect thereto. 3 The opening through the sleeve-like holder conformsclosely to the driver, and therefore, in the present case, it is alsosquare in cross section,

as-shown in Figs. 7 and-8." 7 a The holder.16 is yieldingly mountedrelative to the; driver by .inea'ns of the following mechanism:Depending 1 from the holder sleeve; at opposite sides-are cheeks or arms18 which are guided vertically on the 1 jaw 1i by engaging guide grooves19 on opposite enlarged section on line .Fig. 7 is a planfiviewofaportionofthe:

sidQiQf the'jawt The lowerendsofthe arms 1 18 are interconnected bymeans of a transverse pin 20, engaged by a leaf sprmg '21 which may beconveniently attachedto the against the top surface ofthe driver and itsleg portions held upright by engaging the corners 24 of the squaresleeve opening, as shownin Fig-8. The-staple fits said open ingrather'closely so that when the staple is dropped into the holder itwill be held in a position to-cooperate with the anvillll', ashereinafter described.- V

In the present example, aspecialform of stop is used-to limit the'upwardmovement of the holder (under the influence off'the spring), relative tothe driver. A Ushaped member 25 preferably made of sheet metal" ispivoted on the pin 20 between thecheeks or. arms 18 oflthe stapleholder,- and is provided with surfaces to abut the" lower portion of thej ant-14. Intheform shown, the bent up SlClB'DOlblOIIS 'of the member 25are perforated for the reception of the pin '20, and are provided with-=edge portions 26 whiehabut the lower surface of the aw 14 when theparts are in the position shown in Fig. 2, and therebylimitthe upwardmovement of the holder. The; member 25 is provided with a thumbpieceormanipulating handle 27', by which it maybe swung about the pivot'20into-the position shown in Fig. 5. In this last position, the edgeportions 28 at the ends of the bent'up side members engage thelower-surface'of the jaw 14 and holdthe holder 16 in a: depressedposition. In other words,;the member '25 acts'in the nature of a camwhich,-when swung into one position, will force the holder downwardwithreference to the driver and maintain it in-that position.Inthismanner, the

pocket formed by the cooperation of the driver and the holdermay bevaried-in depth as desired. Where it is :found that the holder 16, whenin its uppermost position- (Fig. 2) is too close to the anvil for theready and convenient insertion of the staple, it-may be easilylowered'into the position shown in Fig. 5 by swinging down the thumb piece 27 sothat theho'lder' will then be more freely accessible. I

Inthe operation ofthe device, the staple is placed in position, asshown-, for example,

in Fig.2. The layersfof material "to be united-Care then interposedbetween the holdervandtheanvil, :and thejaws 13; 14

are .approached toward each other by means of the lever handles. First,the member 15 drives the staple upward through the lay- .ers ofmaterial. During this part of the operation, the staple isfirmly held ontop'of the driver in the proper position by means of the holder. As thefree ends of the staple pass completely through the uppermost layer,they come into contact with the die 17 and are thereby turned over and,down- 81, and the spring 21' returns-the holder 16 to its normalposition. i It has been assumed that in the foregoing ;operation, the"staple engaged the front and rear corners 24 of the holder so as tohave theplane 'ofthe staple in the plane of the tool. If desired toset-the staple transversely of "thetoolgit is engaged in the othercorners 29 of the holder, as shown in Fig. 7 It will be noted that oneof the diagonals of the holder opening is disposed transversely: of thejaw- 14, while the other diagonalis disposed longitudinally of said jaw.The depression or clenching surface 30 of the anvil -17 iscrossshaped,so that the anvil will properly clench the staple when the latter is seteither longitudinally :or transversely-relative to the tool. Thus itwill be :understoodthat the staple can beset when in" differentangular-relations relative to the axis of the driving member. In somecases','the staplecan only be setin ora-pplied' to theshoe Or -otherarticle in-the most advantageous position by disposing it lengthwise ofthe jaws,*but, in other cases, the desired result can-only be obtainedif the staple isdisposed'trans versely of the jaws. My improved tooltakes care ot-both of'these conditions, and provides means for clenchinga staple seatedin a rectangular holder opening coincidentally withone oreither of the diagonals of said o ening. I

It will be observed that th e driver 15-is in theform of a prism, which,in the example shown, is of uniform cross sectionthroughout that partwhich is engaged by the sliding holder 16. Furthermore, the crosssection-ofthe driver is'that of a] convex polygon, i. 6., one withoutreentrant angles,- and the polygon is a regular polygon, 216., one inwhich all the sides and angles are equal. The open-ing'in the bottom ofthe holder is of the same cross section as theiopening through theremaining portion of the holder body, so'that the holder conforms toihedriver throughout the -1ength-of'the former.

renders the manufacture of the driver and.

cooperating holder a very simple matter, at the same time that itprovides for the seating of the staple in either of two positions in therentrant angles of the holder which conform to and guide the holder onthe projecting angles of the; driving member.

Of course, I do not limit myself in all aspects of the invention to aconstruotionin which the holder has only four seating 'cor--.

ners for the staple, for obviously, the number might be varied withoutdeparting from the scope of the invention. Various changes in this andother respects may be adopted within the scope of the appended claims.
